SPINDLE-BEARING FOR SPINNING-MACHINESL SPECIFICATION forming part of Letters Patent No. 354,887, dated December 28, 1886.

Application filed November 5, 1885. Serial No. 181,875. (No model.)

To all whom it may concern:

Be it known that I, HoRxoE' P. Ormsm'a citizen of the United States, residing at New Bedford, in the county of Bristol and State of -Massachusetts, have invented a new and useful To this end my invention consists, first, in

a bolster having a closed bottom in which the spindle is stepped, and its lower end reduced in diameter and provided with oil-holes, and having an elastic or flexible material secured about said reduced portion; second, in a cover for the oil-chamber extending from the under side of the sleeve-whirl to a point on the sides of said chamber; and, third, in providing an automatically-closing oil-hole in said cover.

In the accompanying drawings, Figure 1 represents a spindle in elevation and its sleevewhirl and bearing in vertical section, and also showing my improved bolster and oil-chamber. Fig. 2 represents a View of the under side of the oil-chamber cover; and Fig. 3is an enlarged View in vertical section of my improved bolster.

In Fig. 3, b is the bolster, hollowed out to fit the shape of that part of the spindle which it receives, and having its lower end closed to form a step for the spindle, and the exterior portion,r,reduoed in diameter. Through the sides of the lower end,o,of the bolster is bored a hole or holes, t,in order that oil may be supplied through them to the spindle.

About the reduced lower end of the bolster and covering the holes t is Wrapped and secured an elastic or flexible material, 0', so that when the bolster is placed loosely in the bolster-case c the elastic or flexible material may bear lightly against the sides thereof. Between the bottom of the'bolster and the case is interposed a disk, as, of flannel or felt, or other suitable yielding material.

The cover 6 of the oil-chamber m, Fig. 1, extends from the under side of the sleeve-whirl to a point on the sides of the chamber, and cannot be raised sufiiciently to allow dust or dirt to enter the oil-chamber while the retaining-wire y is turned over'the sleeve-whirl.

The cover e is provided with an oil-hole, g, in order that the oil-chamber m may be charged with oil while the spindle is in motion, thus saving an amount of valuable time. hole 9 is covered on the under side by a piece of spring sheet metal, S, riveted or otherwise suitably secured to the cover, as is fully shown in Fig.2, in which the oil-hole is shown in dotted line covered by the spring S. The cover has a projecting side, 0,notched at Z to engage the retaining-wire y, in order that the cover e may be retained in a proper position, with the oil-hole g in front.

In the bottom of the oil-chamber m, Fig. 1, and through the side of the bolster-case c,is bored an oil-hole, r, in order that the oil from the chamber m may pass into the space between the bolster and bolster-case, and from there through the flexible material ian'd holes t to the spindle. V

In the bottom of the oil-chamber m,I place a piece of flannel,h, or other suitable material, in order that when by the motion of the spindle the oil overflows the top of the bolster and case it will be strained from all impurities 'before being again supplied to the spindle through the oil-holes r and 't.

The bolster b is placed loosely in the bolstercase, and the flexible material about its lower end is made to bear lightly against the sides of said case, in order that the spindle and its load. may adjust itself to its true center of motion. The yielding felt disk w,between the bottom of the bolster and its case,prevents.the spindle from jumping when the spinning-frame receives a jar.

The bolster is retained in the bolster-case and restrained from rotation with the spindle by the spring (I, in the same manner as is shown in my Patent No. 327,137,0f September 29, 1885.

The cover e for the oil-chamber has an an- The oil- .under side of the sleeve-whirl.

nular rim, e, which rises to, or nearly to, the The latter is mounted upon a cylindrical shell, 6 which forms part of the sleeve-Whirl and lies outside of and out of contact with the bolster b and bolster-case 0, whereby any oil carried over the top of the latter will return to the oilchamber m and again pass to the spindle, as described.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent,

1. The combination, with the spindle and bolster-case, of a bolster formed with a closed bottom constituting a step for the spindle,and having its lower end reduced in diameter and provided with an oil-inlet, a flexible absorbent material applied about said reduced end, and

an elastic packing interposed between the end 20 of the bolster; and the bolstercase, substantially as described.

2. The combination, with the spindle, the

bolster, the bolster-case formed with an oilcharnber, m, and the sleeve-whirl supported out of contact with said bolster-case, of the cover e,having an oil-inlet,g,anda central opening provided with an upturned flange extending beneath and exterior to the under side of the sleeve-whirl,and a spring-plate, S, having one end attached to the under side of said cover,with its other end beneath and closing the oil-inlet, substantially as described.

3. The combination, with the bolster having an exteriorly-reduced closed lower end provided with an oil-opening, of the yielding fabric i,surronnding the same, the bolster-case having oil-opening r, the oil-chamber m, porous filling h, cover 0, having oil-opening g, and cover S, substantially as described.
